Iranian researches used nanoparticles to synthesize a new type of absorbent to remove toxic dyes from textile industry wastewater with acceptable quality

TEHRAN (INIC)- Iranian researches used nanoparticles to synthesize a new type
of absorbent to remove toxic dyes from textile industry wastewater with acceptable
quality.

The entrance of the outlet fluids in textile industry to the environment is one
of the important issues. The majority of the synthesized and natural dyes have
complicated aromatic structure molecules, and they are resistant to microbial
and decomposition agents in the environment.

The aim of this research was to present an efficient adsorbent to eliminate
such pollutants from the outlet water of plants and industrial factories
through a new method with high yield.

“In this project we tried to present a method in order to remove water
pollutants, which can be used in water purification systems,” Arezoo Amiri, one
of the researchers of the plan, stated.

In this method, the effective parameters were firstly optimized. Next, the
efficiency of the produced adsorbent was studied and compared to other
adsorbents used for this purpose. Finally, the performance of the nanoparticle
was confirmed.

Nanomaterials are important in chemical interactions due to their high specific
area and the great number of available atoms. This fact increases the
performance of the method and also increases the efficiency. On the other hand,
one of the most important and effective parameters in adsorption method is the
ratio of area to the volume of the adsorbent. This ratio is very high in
nanoparticles.

“Due to their specific characterizations, nanoparticles can increase the
efficiency and performance of the methods. They can also reduce the time of the
process. Therefore, the use of nanoparticles in this method is very
cost-effective,” Amiri added.

Results of the research have been published in Chemical Engineering
Communications, vol. 200, issue 8, 2013. For more information about the details
